Description

For the sake of clarity one can discuss on-line interactive systems with
reference to their technology, their economics, and their application and
utilization, even though all these aspects are obviously intertwined and
inseparable. They will, however, be considered separately.
On-line, interactive systems were conceived long ago, even before
computers. Vannevar Bush's Memex was essentially an on-line interactive
system, as were the first teaching machines. What is considered the first
computer-based interactive systems were implemented by M. I. T. in its SAGE
system which responded to RADAR signals. From a practical, economically
feasible point of view, however, certain technological developments were
necessary before on-line processing could be widely adopted.
